The screenshot below shows a Sumo Paint editing session, in which I opened up a photo from my Flickr account. Sumo also allows you to upload and edit photos from your own hard drive, or your optional Sumo account (click to view a larger version).

You can then save the edited image to your hard disk, or to your Sumo account.

The site doesn’t require registration, and you can use the application immediately once the Flash components have been downloaded and cached on your computer.. Subsequent application launches are much faster.
